My understanding: you can run a mixed mode environment, with Oxigen and N-Digital cars on the track at the same time.
The Ninco LCs need the Oxigen add-in board, and you have to use the N-Digital console to deliver power to the track. (So it doesn't really help with the OPs power issues.)
You can then race N-Digital cars and Oxigen cars on the same track at the same time. Each Oxigen car will still need a slot.it controller and wireless cartridge. You have to add trackside magnets for lap counting the Oxigen cars and a suitable RMS- e.g., PCLapcounter- to track both Oxigen and N-Digital cars.
